• 背景

通过EasyExcel进行多个ExcelTypeEnum.XLSX类型Excel写入ZIP流时会发生Stream closed异常，以下通过使用ByteArrayOutputStream字节数组输出流完成多Excel.XLSX类型的压缩并输出

1、引入相关依赖（easyexcel）

com.alibaba

easyexcel

2、定义数据模型(ExcelData)

@Data

public class ExcelData {

private String name;

private int age;

2、定义将excel文件写入指定输出流方法

private static void writerStream(OutputStream outputStream) {

ExcelWriter excelWriter =EasyExcel.write(outputStream,ExcelData.class)

.excelType(ExcelTypeEnum.XLSX).build();

WriteSheet writeSheet = EasyExcel.writerSheet("sheetName").build();

excelWriter.write(getData(), writeSheet);

excelWriter.finish();

3、执行main方法

public static void main(String[] args) throws IOException {

FileOutputStream fos = new FileOutputStream(filePath);

ZipOutputStream zos = new ZipOutputStream(fos);

ByteArrayOutputStream baos = new ByteArrayOutputStream();

writerStream(baos);

ZipEntry zipEntry = new ZipEntry("第一个excel.xlsx");

zos.putNextEntry(zipEntry);

zos.write(baos.toByteArray());

baos.reset();

ZipEntry zipEntry2 = new ZipEntry("第二个excel.xlsx");

zos.putNextEntry(zipEntry2);

baos.close();

zos.close();
